vTo' all whom t may concern."

Be yit lmown ythat we, WILDEYMERLIN PORTER and EDWARD HARMOND SPRAGUR, both citizens ofy the United States',y residing at Sacramento, in the countyk of Sacramento `and State of' California, :have invented new and useful Improvements in Repair- Benches, of which the following is a specifi'- catiOn. l K

This' invention relates to a' repair bench and particularly pertains to i'neans` for the ready'repair of automobile radiators.

KDue t0 thedifiiculty Iwhich"automobile repair men have had in procuring proper equipment for testing and repairing automobile radiators, itr has beenfound desirable to produce a bench especiallydesi'gned for lhandling automobile radiators, and which is equipped with theproper accessories for repairingand testing theradiators. L K It is the principal object of the present invention, therefore, to provide a benchfof simple (construction,y fitted [with Vmeans for ktesting automobile radiators 'andwhich is also supplied, with blow torches and repair tools by 4which the various joints of Ka 'raydiato-rmay,be reached and sealed.

VyThe present invention contemplates the useofa radiator bench formed with a'tank largeI enough to .receive` aradiator and adapted to carry suiiicientwatertofpermit the radiatorv to be completelyv submerged therein, and this tank isprovided with a removable cover whichY will supplement the bench and allow the bench structure to,- be used without reference toy thetank.

Mounted beneathffthe testing tank is an air supply reservoir and in connection with this reservoir,an air pump is providedto provide air under pressure by which.-the tank may be tested. Mounted upon the end of the bench are suitable repair and testing tools by which the repairs may be easily made.

-The invention is illustrated by way of eX- ample in the accompanying drawings, in which- Figure 1 is a view in side elevation, showing the complete bench with parts bro-ken away to more clearly disclose a support for the tank cover.

Fig. 2 is a view in plan, illustrating the complete invention.

Fig. 3 is a View in vertical section, as see on the'line 3-3 of Fig. 1, showing the tank,

in operative relation to the pipe 19 and 1nthe radiator supporting `arms and the sup- '.reservoir therebeneath. l 'K F1g 4f' lsfa vlew'finvertical section on "Kline of Fig.1,showingthe location of the airpump.

' Referring to the drawings, f 10 indicates 'laA bench which is mounted upon a seriesof supporting/legs `11. The bench-'is formed vwithKa rectangular opening l2 at one kend "thereof, ladaptedto*accommodate a testing tankfISi" This tank isl clearly shown in Fig. 3 as beingmetaldined inside and being of ja ,depth suflcient to accommodate an y automobile radiator. jThe 'rectangular opening 12 inthe benchis partially closed by la support board 14:'. kThis board fits within the opening an its upper surface lies flush with the surfacey of the bench. This provides'aibenchhaving a largeworking area for usewhen'a 'radiatoris tested.- Apluyralityofi-bars 15 are secu-red to the ends of thefsupport'board and act to support the same, as indicated in Fig. 1.

Properly supported beneath the tank 13 is an air supply reservoir 16. This reserl'volr isi in communication with .an air pump- 17 which is supported upon the platform 18fixed beneath the end of the bench. This fair pump ymay beof any suitable design yand yis here shown as connecting with the reser- ,voir lby means of a pipe 19. This plpe also yextends upwardly and is fitted withvan outlet tube 2OV carrying a regulating valve 21.

VOn the rendl' of this tube va hose connection y22. is provided.-v Thisconnecting member is adaptedto bepositioned within the opened mouthfofl an y, automobile radiator and to supply it with` suflicient air under pressure to locatelthe leaksv and to test the strength An air gage 23 is secured dicates a pressure exerted by the air within the radiator. Mounted upon the edge of the work-bench is a small furnace 24 which is provided with gaseous fuel by means of a main 25. This pipe also connects with a blow torch 26 which is tted wKith an air connecting tube 27 receiving its supply from the reservoir 16.

Secured `Ibeneath the tank are a pair of sliding arms 28. These arms are carried m channel members 29 and are adapted to be drawn outwardly at the side of the bench when Va radiator is being tested. makes it possible to turn the radiator n various CII positions and to reach all ofV its seams so thatrepair can be more easily made than would be possible if it w'e'zre laid upon a fia l bench.

In the operation of the present iniention,

the radiator is repaired upon thel bench 10"V and thereaiiter may be tested by removing the cover 14 of the bench and suibmerging the radiator in a body of water4 contained within the tank 13. At this time the hose connection 22 has been secured tothe radiator and the pressure ofi the; ai-r- Within `the circulating passages of the radiator' will .cause bubbles tov appear in the'water at. the points of leakage. This insures that the necessary repairs may be easily made; when thus located. In order to test 'the radiator forv pressure, the valve 21 mayl be opened and the pressure read upon the gage 23. If further repair is required, thejsupportin arms 28 may be drawn from beneath t e tankandthe lblow torchandl furnace used as needed. f

It will thus` be seen that the bench here disclosed is particularly adapted and `equipped for the testing and repair of radiators and combines the necessary-tools and testing means therefor.

Vhile we have shown the preferred form of our invention, it will be understood that various changes/in the` combination, constructionv andy `arrangement of .parts may be made by those skilled in theart,` without dep a-rtinrT from the spirit of theinventionas claime Having thus described our invention, what we claim and desire to secure by Letters Patent is- 1. A radiator testing bench comprisingY a flat Working'bench, a tank in one end' thereof and` of suiicient dimensions lto permit a radiator to be submerged therein, anda selfcontained air supply unit carried by the bench and for connection with the .radiator to be tested.

2. A radiator repair bench comprising a fiat work bench, leg'ssupporting the same, a rectangular `opening in onev end of said bench, a removable cover for said opening, a testing tank beneath said cover,A an air reservoir secured beneath the tank, an air pump mounted 'beneath the bench and in Vcommunieation nwith said reservoir, and Vpressure deliverlng and regulating means adapted to be connected with a radiator to be ilzested while it is submerged within the tan` .f

3. A radiator repair bench comprising a flat work bench,` legs supporting the same, a rectangular lopening in one end of said bench,- a removable cover for said opening, atesting tank 'beneath said cover, an arr reservoir secured beneath the tank, anl air pump vmounted beneath the bench and in communication with said reservoir,.pressure delivering and regulating means adaptedto be connected with a radiator to be tested while itis submerged within the tank, and extension arms secured beneath the tank'and adapted. to `be drawn therefrom, for theswp- .port of .a radiator.

, 4. A radiator repair bench comprising a flat work bench, legs supporting the same, a

rectangular opening 1n one end vof lsaid bench, a removable cover for saidV opening, a testing tank beneath said cover, an air reservoirsecured beneath the tank, an air pump mountedVV beneath the bench l and in communication with said reservoir, pressure delivering and regulating means adapted to beconnected with a radiator to be tested while it is submerged within the tank, extension arms secured beneath` thle tank and adapted to be drawn therefrom for the support of a radiator, and a blow torch connected with a supply of fuel and connected with the air reservoir.

In testimony whereof we have hereunto set our hands in the-.presence of two subscribingr witnesses.
